.VEHICLE SASH CONSTRUCTION.

Application filed February 14, 1922. Serial No. 536,481.

1 and more particularly to provide a sash construction and mounting whereby looseness and rattlin incident to the vibration of the vehicle, and the tendencyof the glass or like .material forming the light, may be prevented, whereby the sliding movement of the sash in opening and closing the same may be facilitated, and whereby wind and rain may be effectively excluded when the sash is in the closed ition without involving any difiicult 1n the opening and closin movements 0 the sash and without necessitating the special adjustment or arrangement of any auxiliary weather strip or joint closing feature; and with these objects in view the invention consists in a construction andcombination of parts of WhlCll a preferred embodiment is shown 1n the accompanying drawin wherein:

Figure 1 is an e evation of a sash constructed in accordance with the invention and formed as a part of a conventional door of the type used in connection with closed vehicles.

Figure'2 is a vertical sectional view of the same.

Figures 3 and 4 are detail sectional views respectively on the planes indicated by the lines 3-3 and 44 of Figure 1.

The sash is composed of a metallic frame of which the members representing the several sides of the rectangle areprovided with inner grooves 11 and outer grooves 12,

and a glass sheet or plate 13 forming the window, light of which the edges are seated in a ved cushion fitted in the inner groove 11 of the frame, said cushion for example consisting of rubber and hem arranged in the groove of the frame u n er a sufiicient compression to snugly gnp and form an air tight contact with the engaged surfaces of the sash light. The outer groove in the sash frame is fitted with a yielding cushion 15 of felt or its equivalent, longitudinally grooved as indicated at 16 to receive the flat blade-like wing 17 of a guide secured to the door or vehicle frame 18, and having a. base flange 19 attached by suitable fastening means to said door or vehicle frame. A molding or bead 20 secured to the door or vehicle frame in overlapping relation with the edges of the sash frame serves to conceal the joint between the latter and the door or vehicle frame and substantially conceal the guide upon which the sash frame is mounted.

Obviously at the uper and lower edges of the-sash the frame thereof may as indicated in the drawing and. particularly in Figure 3 thereof consist merely of the inner grooved or chambered element 11 for the reception of the yielding cushion 14: to receive the adjacent edge of the window light, but associated with the lower edge of the sash there is arranged a weather strip 21 consisting of a plate extending downward through the slot 22 provided for the lowering of the sash and adapted to bear against the edge of the sill 23, said plate having an L-shaped retaining flange 24 which is seated in the groove or channel of the sash frame and secured in place by the cushion in which the edge of the sash light is seated. The weather strip is therefore held in place by the cushion which seats the sash light and the downwardly and outwardly inclined leaf 21 thereof serves to effect a yielding contact with the edge of the sill to prevent access of wind and rain to'the interior of the vehicle.

In the construction illustrated the sash frame consists of folded sheet metal which is doubled upon itself to form the side walls of the sash light seat in which the light holding cushions are fitted, and which is deflected and directed inwardly at its edges to form flanges 25 which engage the cushion 15 which seats the guide wings 17, so as to hold said cushions in position against displacement by reason of frictional contact with the guide wings in the opening and closing movements of the sash.

'From the above description it will be obvious that while comparatively of light construction in weight a sash of the type indicated is protected against rattlingor breakage incident to the vibration of the car or the slamming of the door, and at the same time is adapted to exclude air and rain without affording any undue resistance to the sliding movement thereof when constructed and designed for displacement to afford a circulation of air through the car.

Having described the invention, what is claimed as new and useful is 1. A sash for vehicle tops having a sliding frame provided with an inwardly directed groove or channel fitted with a yieldingloushion for seating the edges of a sash lig t, and a weather strip having a downwardly and outwardly inclined wing ex-' tending into the sash receiving slot to bear against the outer wall thereof and provided with an inner eross-sectionally L-Shap- 0 retaining flange seated in the groove or chanmauve nel between the walls thereof and the light seating cushion. Y

2. A sash for vehicle tops having a sliding frame provided with an inwardly directed groove or channel fitted with a yielding cushion for seating the edges of a sash light, and a weather strip having a downwardly and outwardly inclined wing extending into the sash receiving slot to bear against the outer wall thereof and provided with an inner cross-sectionally L-shaped retaining flange seated in the groove or channel between the walls thereof and the light seatiljlig cushion, said wing being resilient to e eat a yielding contact with the outer wall of the sash slot.

In testimony whereof he afixes his signature.
